Sintering products molded by injecting ceramic and metal powders

Abstract

The injection molding products with different volume ratios of ZrO₂ ceramic powder to 316L stainless steel powder were prepared. Properties and structure of the products were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). The results show that the compressive stress exists in the products and the bend strength reaches 300 MPa. ZrO₂ phase and stainless steel phase are uniform in samples. The toughness of ceramic increases with the increasing the content of stainless steel. Through TEM study of the interface, some crystalline orientation relationships are determined.
